COP-BUILDING MECHANISM FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 465,217, dated December 15, 1891. Application filed December 16. 189i). Serial No. 374,861. (No model.)

To all whom it may concern.-

Be it known that I, HENRY C. SPENCE, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Cop-Building Mechanism for Spinning- Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object to so construct the builder motion of a spinning-frame that with but slight changes, easily and quickly made, the same frame may be made to wind bobbins both for warp and for fill-ing.

To accomplish this object in this my present invention I have provided one of the usual intermediate gears employed in the train of gearing for driving the usual rolls with a shaft, and have provided this shaft with a bevel-gear which may mesh with a gear of one or another number of teeth on the waveshaft employed to actuate the building-cam shaft, such gears enabling me to readily change the speed of the builder-cam shaft and its operative cam according to the work to be done, I having herein shown the gears on the said wave-shaft as a double bevel-gear. The builder-cam shaft, as shown, has a wormgear engaged by a worm on the worm-shaft, and also two cams side by side, one a heart, it being of suitable shape to efiect the warpwind, and the other being three-pointed to effect the Weft-wind. The builder-lever is made in two parts, one part having a stud to be acted upon by the heartcam and the other a stud to be acted upon by the three-pointed cam, the said parts being adjustable to place either of the said studs as desired, in proper position to be acted upon by its proper cam. This lever is adapted to receive either a segmental rack, as when winding warp-bobbins, or a gear, as when winding weft-bobbins, the usual chain or equivalent device attached to the rocker devices being attached to either this rack or this gear.

Theparticular features in which my invention consist will be hereinafter described, and pointed out in the'claims at the end of this specification.

Figure 1 in broken elevation represents a sufiicient portion of the head end of a spinning-frame to enable my invention to be understood; Fig. 2, a partial front side view of the machine shown in Fig. l, the parts contained in thisand in Fig. 1 being thus adapted for winding bobbins-with a warp-wind. Fig. 3 is a somewhat enlarged detail of the builderlever and the cams, the builder-lever carrying, however, the gear in place of the rack, as it will do when the machine is to be employed for winding a weft-bobbin; Fig. 3, a modified form of builder-cam. Fig. 4 is a top or plan View of the parts shown in Fig. 3 with the cams omitted; Fig. 4:, a section in line 00 Fig. 3. Fig. 5 is a sectional detail show ing the driving source for the wave-shaft, the

bin of the same character, it having straight sides wound with weft-yarn. Fig. 13 shows a weft-bobbin havinga truncated base wound with weft, the latter bobbin being adapted for the loom-shuttle.

Referring to the drawings, the frame A, the

roller-beam A, the band-cylinder A for driving the spindles, the gear A thereon engaging the jackgear A on a shaft, having a change-pinion A which engages the intermediate gear A and the second intermediate A", the said intermediates A and A driving the usual rolls, are and may be all as shown, as may also be the ring-rail B, the lifting-rod B, and the rocker-shaft B The builder-cam shaft B has fast upon it the heart-cam F, employed when the bobbins are to be wound for warp, as in Fig. 11, and, as herein shown, the hub of this cam F has fast upon it the weft-cam G, the connection being made by a usual bolt or key G.

I have provided the usual intermediate A with a short shaft a, upon which I have adjustably secured by a set-screw a a bevelgear a-*, thesaid bevel-gear being adapted to engage the outermost circle of teeth 2 of the bevel-gear 13*, fast upon the upper end of the wave-shaft O, or the series of teeth 3 of aless number, forming, as herein shown, a part of the same gear, the gear a having preferably about thirty teeth, the series of teeth 2 having about fifty-two teeth and the series of teeth 3 about thirty-two teeth, so that when dition it is supposed that the frame is wind ing warp-bobbins, but in Fig. 5 the gear a by its dotted-line position is shown as in mesh with the series of teeth 3, and at such time it is supposed that the machine will wind weftbobbins.

The gear B is provided with a set-screw a to hold it in adjusted position and enable it to be moved upon the shaft 0 when changing the gear a to one or the other of the series of teeth 2 or 3. The wave-shaft C is provided with a worm D, which engages the usual wormtoothed gear E, fast on the builder-cam shaft B To a cross-girt D of the frame by bolt a I have oonnected in adjustable manner a stand a which receives a rock-shaft a to which is secured the builder-lever H H, the said builder-lever being a compound lever connected by a bolt a The arm II near its forward end is grooved at its inner side to receive the slotted plate 01., having the stud N, which is acted upon by the warp-cam F when the machine is being'used to wind bobbins for warp, (see Fig. 11,) the said plate 'n being connected in an adjustable manner to the said arm H by means of a bolt a carried by the said arm and extended through a slot at in the arm H.

Figs. 1 and 2 show the stud N in proper position tobe acted upon by the warp-cam F; but in Figs. 3 and 4 the plate n is shown as moved forward upon the arm H for a sufficient distance to remove the stud N from the path of motion of the cam F, it occupying such position when the weft-cam Gis operating, as will be described.

The builder-lever referred to has suitable bearings, for the reception of the usual shaft M, having the worm 'm and the ratchet-gear a ,and in practice this ratchet-gear is moved step by step in usual manner common to spinning-frames, as in United States Patent No. 222,330. The arm H of the builder-lever is suitably grooved (see Fig. 4) for the reception of segmental rack O, and the arm has a lug 0, through which is extended. the bolt a, (see Figs. 1 and 2,) which holds in place the segmental cap 19, which retains the segmental rack O in place upon the builder-lever, but

out into the position Figs.

so that it can be moved therein longitudinally by the action of the worm m in engagement with its teeth. The arm H also hasconnected to it by bolt 0. the slotted plate 1, having a stud I, which plate, when the machine is being used, as in Figs. 1 and 2, to wind Warpbobbins, is turned over back about the bolt 0. as a center, as in dotted line, Fig. 1, thus placing the stud I out of the path of movement of the weft-cam G; but when the machine 1s to wind weft-bobbins and the stud N is drawn 3 and 4, as described, then the plate 2 is turned over forward from the position Fig. 1 into the position Figs. 3 and 4, so as to be acted upon by the weft-cam G.

The lifting-rod B has at its lower end a shoe S, connected thereto by a set-screw s, the said shoe being of usual construction.

I have made some improvements in the rocker levers or arms to which the rockershaft is connected, especially the rocker-lever for operating the chain or equivalent a. The rocker-shaft 00 which may be as usual, has an arm (1, to which is connected in adj ustable manner by bolts a an arm 7,111 the outer end of which I have placed a stand W,

- having a threaded shank a provided with {adjusting-nuts V, one above and one below i the arm W, so that the said stand can be adjusted vertically in the arm W, the arm WV being adjustable longitudinally. The stand W carries a roll T, which acts upon the shoe S, and for the best results this roll should act.

upon the shoe centrally when the ring-rail B i is in its central position, so it will be under-. stood that with bobbins of different length, or where the wind upon the bobbins is to be varied in l'ength,I may adjust the stand ver-.

tically and at the same time adjust the arm WV longitudinally,to thus keep the proper relative positions of the parts according to the bobbin being wound, it varying as to the length of the traverse. The shaft 00 has asecond arm (1 to which is adj ustably connected by a bolt a an arm Z, having an ear (1 in which is adj ustably mounted a chain-holder Y, the adjustment of the chain-holder being efiected by means of two set-nuts a to thus regulate the traverse of the ring-rail to the particular bobbins used,it being a fact that bobbins in difierent mills vary in length, and the adjustment of the chain enables the traverse of the ring-rail to be adapted to the particular length of bobbin. The chain a is connected at one end to this chain-holder, and at its opposite end it is connected to a hook at", in turn pivoted uponthe rack 0 when the latter is used; but when the cam G is operated, then the end of the chain a is connected to the end most link d of a chain (1 (shown as fastened by a screw (1 to the hub of the worm-pinion J, to be described.) The arm Z is provided with a curved rest or guide Z, having a flange, over which the said chain a. is passed, the chain be as usual.

IIO

When the machine is to be used for winding weft-bobbins, the bolt a is removed,taking off the cap-plate p, and the segmental rack O is drawn out, the chain at being disengaged from the hook at". This done, the worm-pinion J is secured to the ear 0 of the arm II by a bolt K, and. the chain a is connected to the chain d, the worm m on the shaft M engaging the worm-pinion J and rotating the same step by step, unwinding the chain d from the hub of the worm-pinion J intermittingly as the bobbin is filled, to thus change the startingpoint of the ring-rail in its upward movement prior to applying each layer of yarn, this variation in traverse being, as shown, to wind the weft.

A machine provided with my improvement may be changed from the warp to the filling wind, or vice versa, ordinarily in less than five minutes, it being necessary only to shift the plates at or d, as stated,and to change the segmental rack for the worm-pinion, or vice versa, and to change the meshing of the gears,

a and B Prior to my invention I am not aware that the builder-cam shaft of a spinning-frame has ever been provided with a warp and a weft cam adapted to operate,.as desired, upon studs mounted upon one and the same builder-lever, so that this invention is not limited to the particular shape of the builder-lever or of the mannerin which the studs to be acted upon by the said cams are connected to or made adjustable on the said builder-lever, as the particular construction of these parts might be variously modified without departing from the gist of my invention.

While for simplicity I prefer the employment of the gears a and B in order to gain a diiferent speed forthewave-shaft from the constantly-moving intermediate A common to spinning-frames, yet this invention is not limited or intended to be limited to the exact construction of gearing shown, as instead I might employ any other well-known equivalent devices, whereby a difference in speed between the shaft a and the shaft O may be gained, there being many such devices well known to mechanics.

The three-pointed cam G, when shaped as in Fig. 3, will wind a weft or shuttle bobbin, as in Fig. 1-3, and as the grade of each half of each point of the three points is the same the speed of the ring-rail in its ascent and descent will be the same, the time in practice being about forty seconds in ascending and forty seconds in descending.

In some classes of work it is desired when the rail is rising to so wind the yarn as to formv of that layer a binder to prevent the yarn shelling off or tangling when the bobbin is in the shuttle. To do this and wind the yarn make a binding-layer, the less steep grade letting the rail down slowly to wind theyarn closely.

I claim 1. A spinning-frame containing the following instrumentalities, viz: a builder-cam shaft, a gear thereon, a wave-shaft having a worm, an intermediate gear, as A, its shaft a, and

intermediate gearingbetween the said shafts the worm-shaft M, having the worm m, to operate substantially as described.

4. A spinning-frame containing the following instrumentalities, viz: abuilder-cam shaft, builder-cams F and G thereon, and means to rotate the said shaft at different speeds according to which cam is to operate the builder-lever, combined with a builder-lever provided with adjustable studs adapted to be put into or out of operative position with relation to one or the other of the said cams, to operate substantially as described.

5. In a spinning-frame, the combmatlon, with the ring-rail and lifting-rod provided with a shoe, of a rocker-lever having an arm provided with a vertically-adjustable stand containing a roll to act upon. the said shoe and with means to adjust the said arm long1- tudinally, as and for the purpose set forth.

6. In a spinning-frame, the combinatlon, with the ring-rail and-lifting-rod provided with a shoe, of a rocker-lever having an arm d an arm Z, longitudinally adjustable thereon, and a chain-holder mounted on said adjustable arm Z to shorten the effective length of the chain and thereby regulate the traverse of the ring-rail to the bobbins used, substantially as described.

7. A spinning-frame containing the followinginstrumentalities, viz: abuilder-cam shaft, a gear thereon, a wave-shaft having a worm, an intermediate gear A, its shaft a, the adjustable bevel-gear a on said shaft, and the bevel-gear B adjustable on the shaft 0, provided with two concentric series of teeth.

equidistant from the shaft a, whereby the speed of the shaft 0 and consequently of the builder-cam shaft may be readily changed, substantially as described.

In testimony -whereof I have signed my name to this specification in the presence of two subscribing witnesses.
